<p>A receiver having an enhanced cell search accuracy of three-step cell search. The receiver comprises a matched filter (MF) to which a received signal Sin is inputted and a sliding correlator unit (SC). The matched filter (MF) calculates the correlation between the received signal Sin and a first synchronization code PSC. The output Spsc is held in a memory (MEM1) and thereafter processed by a timing detecting part (TDP). The sliding correlator unit (SC) comprises sliding correlators (SC1 to SCq). The outputs (A[1] to A[q])are held in a memory (MEM2) and thereafter processed by a timing group identifying part (TGI). The sliding correlator unit (SC) calculates correlation by using first and second synchronization codes or only the first synchronization code. When using the first and second synchronization codes, the sliding correlator unit (SC) performs channel inference and phase correction and performs common-mode addition. When using only the first synchronization code, it performs only common-mode addition.</p> |
